Javascript中实现JSON数组多键值排序

 

 ①Json数组准备

var menuData1=[

{"orderid":-10,"text":"主页","title":"个人网站主页","url":"Default.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":10,"text":"个人新闻","title":"个人新闻","url":"News.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":5,"text":"发表论文","title":"发表论文","url":"Paper.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":2,"text":"出版专著","title":"出版专著","url":"Monograph.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":7,"text":"参与项目","title":"参与项目","url":"Project.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":8,"text":"个人荣誉","title":"个人荣誉","url":"Prize.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":1,"text":"发明专利","title":"发明专利","url":"Patent.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":0,"text":"文件共享","title":"文件共享","url":"FileShare.aspx?TeacherID=153","visible":true,"target":"_self"}

];

②这时需要先将数组按orderid升序排序，注意，sort方法会改写原来的数组：

 
menuData1.sort(function(a, b) { return a.orderid > b.orderid ? 1 : -1;} );//升序

③经过排序后，结果为：

 

menuData1=[

{"orderid":-10,"text":"主页","title":"个人网站主页","url":"Default.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":0,"text":"文件共享","title":"文件共享","url":"FileShare.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":1,"text":"发明专利","title":"发明专利","url":"Patent.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":2,"text":"出版专著","title":"出版专著","url":"Monograph.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":5,"text":"发表论文","title":"发表论文","url":"Paper.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":7,"text":"参与项目","title":"参与项目","url":"Project.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":8,"text":"个人荣誉","title":"个人荣誉","url":"Prize.aspx?TeacherID=153","visible":true,"target":"_self"},

{"orderid":10,"text":"个人新闻","title":"个人新闻","url":"News.aspx?TeacherID=153","visible":true,"target":"_self"}
